CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. §119(e) to U.S. provisional application no. 61/237,866, filed Aug. 28, 2009, the entire contents of which is hereby incorporated by reference.

The invention relates to a flavoring mixture comprising one or more sweet-tasting substances as well as phyllodulcin. This flavoring mixture is suitable as an intermediate product for an orally consumable product containing a flavoring mixture of this type, the proportion of conventional sweet-tasting substances in the orally consumable product being reduced. The invention also relates to a process for the production of a reduced-sweetener, orally consumable product and to the use of a corresponding flavoring mixture for the preparation of a product of this type.

Consumers generally have a strong preference for foodstuffs or indulgence foods and also drinks and other orally consumable products which have a high sugar content (particularly sucrose=(saccharose), lactose, glucose or fructose or mixtures thereof) due to the sweetness thereof. On the other hand, it is generally known that a high content of readily metabolizable carbohydrates causes a steep rise in blood sugar levels, leads to the formation of fat deposits and ultimately can result in health problems such as overweight, obesity, insulin resistance, age-onset diabetes and complications thereof. Another particular aggravating factor is that many of the above-mentioned carbohydrates can also have an adverse effect on dental health, as they are decomposed by specific types of bacteria in the oral cavity into lactic acid, for example and can attack the enamel of milk teeth or adult teeth (caries).

Therefore, it has long been an objective to reduce the sugar content of foodstuffs and/or indulgence food and drinks as far as possible, the preferred objective being to achieve this reduction while diminishing the sweetness sensation as little as possible. A suitable measure is to use sweeteners: these are chemically uniform substances which themselves have no, or only a very low calorific value, while at the same time providing a marked sweet taste sensation; in general, the substances are non-cariogenic (a review can be found, for example in Journal of the American Dietetic Association 2004, 104 (2), 255-275). Due to their low application concentration, non-nutritive, high-intensity sweeteners are indeed very suitable for introducing sweetness into foodstuffs, however they often exhibit problems in respect of taste due to dissimilar time-intensity profiles compared to sugar (for example sucralose, Stevia products, rebaudiosides, steviosides, cyclamate), a bitter and/or astringent aftertaste (for example Acesulfame-K, saccharin, Stevia products, rebaudiosides, steviosides), pronounced additional flavor sensations (for example glycerrhyzic acid ammonium salt). Some of the sweeteners are not particularly heat-stable (for example thaumatin, brazzein, monellin), are not stable in every application (for example aspartame) and some have a very long-lasting sweet effect (strong sweet aftertaste, for example saccharin, Stevia products, rebaudiosides, steviosides).

Another possibility—without using non-nutritive sweeteners—is to reduce the sugar content of foodstuffs and/or indulgence foods and to add substances which are sensorially faintly detectable or undetectable and which indirectly or directly enhance the sweetness, as described, for example in WO 2005/041684. However, the substances described in WO 2005/041684 are explicitly of a non-natural origin and thus, from a toxicological point of view, are more difficult to assess than substances of a natural origin, particularly if the latter occur in foodstuffs or indulgence foods or originate from raw materials for the production of foodstuffs or indulgence foods. EP 1 291 342 describes such substances of a natural origin (pyridinium betaines); however, these substances do not influence the sweet taste selectively, but also influence other taste flavors such as umami or saltiness. Furthermore, the disclosed substances can only be purified with great effort.

WO 2007/014879 A1 recommends the use of hesperetin to enhance the sweet taste of reduced-sugar preparations used for nutrition or enjoyment. However, an occasional disadvantage when using hesperetin is its low solubility, particularly in clear, aqueous applications (for example clear cola or still lemonade) and the relatively indistinct sweetness enhancement in acidic foodstuffs and indulgence foods. WO 2007/014879 A1 discloses the use of hesperetin when also combined with 4-hydroxydihydrochalcones. In this respect, it is possible to achieve significant reductions in the quantities of sugar or sweetener with the same sweetness and a substantially adequate solubility, but in many cases it is not possible to reproduce the sweetness with more than a 25% reduction of the sugar and sweetener quantities particularly in strongly acidic (pH<5) applications.

The isocoumarin phyllodulcin which occurs in Hydrangea dulcis leaves has already been described as a sweetener (Kinghorn, A. D. and C. M. Compadre (2001). “Less common high-potency sweeteners.” Food Sci. Technol. (N.Y.) 112 (Alternative Sweeteners): 209-233, Crosby, G. A. (1976). “New Sweeteners.” Critical Reviews in Food Science and Nutrition (June): 297-323). However, the use as a synergistically effective flavoring in particular under the actually only sweet-tasting effect has not been described before.

In fact, JP 11253128 does describe a synergistic combination of Euonymus tricocarpus with Hydrangea dulcis extracts. However, it emerges from the text that the antioxidative action is the primary effect.

In WO 2005/020721, a drink with a combination of a sweetener, monatin, with phyllodulcin as isolated sweetener is claimed. However, in this case the concentration of phyllodulcin is sufficient to produce a sweet taste even on its own.

WO 2007/121604 describes a process for the identification of modulators of the T1R2-TMD and/or CFR:T1R receptors. Phyllodulcin is also stated in a long list of potential test candidates. However, the document does not give sufficient indication that phyllodulcin could be an enhancer of the receptor systems to be tested, as this compound is merely described as a potential modulator. In particular, the document contains no indication that phyllodulcin could have a synergistically enhancing effect on the sweetness perception in vivo. The mentioned document does not even suggest in which ratios phyllodulcin and sweeteners which may be enhanced should be used in vitro or in vivo.

Against the background of the prior art, the object of the invention was to provide orally-consumable, sweet-tasting products which have a reduced amount of sugar and/or sweetener compared to products with a comparable sweetness sensation. Part of this object was to provide corresponding pre-products or intermediate products in the form of flavoring mixtures which can be used in the orally consumable sweet-tasting products in dilute form and which guarantee the desired effect. The products or flavoring compositions should preferably be stable in respect of the sweetness sensation they impart, the sweetness sensation should be based on naturally occurring compounds and/or the reduction of the quantity of sugar or sweetener should be possible while the sweetness sensation remains the same, without the usual flavoring profile being adversely affected. It was further desired that the agents that allow a reduction in the quantity of sugar or sweetener should be effectively and clearly soluble in water.

This object is achieved in respect of the pre-product or the flavoring mixture by a flavoring mixture comprising

-   (i) one or more sweet-tasting substances, selected from the group of     naturally occurring sweet-tasting substances and the physiologically     compatible salts thereof without phyllodulcin and the     physiologically compatible salts thereof,     and -   (ii) phyllodulcin and/or one or more of the physiologically     compatible salts thereof,     -   wherein the ratio of the sucrose equivalence of the         concentration of the substance or substances of group (i) to the         sucrose equivalence of the concentration of the substance or         substances of group (ii) is ≥2, preferably ≥3, more preferably         ≥4 and particularly preferably ≥6.

The sweet-tasting substance or substances (substances of group (i)) are preferably selected from the group consisting of

-   a) carbohydrates, preferably selected from the subgroup consisting     of sucrose, trehalose, lactose, maltose, melizitose, melibiose,     raffinose, palatinose, lactulose, D-fructose, D-glucose,     D-galactose, L-rhamnose, D-sorbose, D-mannose, D-tagatose,     D-arabinose, L-arabinose, D-ribose, D-gyceraldehyde and     maltodextrin; -   b) naturally occurring sugar alcohols selected from the subgroup     consisting of glycerol, erythritol, threitol, arabitol, ribitol,     xylitol, sorbitol, mannitol, maltitol, isomaltitol, dulcitol, and     lactitol. The carbohydrates can also be present in the form of plant     preparations containing one or more of the mentioned carbohydrates,     preferably in a proportion of at least 5% by weight, preferably at     least 15% by weight). The carbohydrates can also be present as a     naturally occurring or artificially produced mixture (for example     from honey, invert sugar, syrup, high fructose corn syrup); -   c) naturally occurring sweeteners, selected from the subgroup     consisting of miraculin, curculin, monellin, mabinlin, thaumatin,     curculin, brazzein, pentadin, D-phenylalanine and D-tryptophan; -   d) naturally occurring sweeteners, selected from the subgroup     consisting of stevioside, steviolbioside, rebaudioside A, further     stevilglycosides such as rebaudioside B, rebaudioside C,     rebaudioside D, rebaudioside E, rebaudioside F, rebaudioside G,     rebaudioside H, dulcoside and/or rubusoside, oslandin, polypodoside     A, strogin 1, strogin, 2 strogin 4, selligueanin A,     dihydroquercetin-3-acetate, perillartin, telosmoside A₁₅, periandrin     I-V, pterocaryosides, cyclocaryosides, mukuroziosides,     trans-anethol, trans-cinnamaldehyde, bryosides, bryonosides,     bryonodulcosides, carnosiflosides, scandenosides, gypenosides,     trilobtain, phloridzin, dihydroflavanols, hematoxylin, cyanin,     chlorogenic acid, albiziasaponin, telosmosides, gaudichaudioside,     mogrosides, hernandulcin, glycyrrhetinic acid; -   e) the physiologically compatible, sweet-tasting derivatives of the     members of subgroups a) to d); and -   f) the physiologically compatible salts of the members of     subgroups a) to e), in particular the potassium, sodium, calcium or     ammonium salts thereof.

The sweeteners mentioned in subgroup d) can preferably be present in the form of extracts or fractions which are obtained from natural sources and contain the sweet-tasting amino acids and/or proteins.

Naturally occurring sweeteners in the context of the invention are non-nutritive or only slightly nutritive, in particular sweet-tasting compounds or particularly sweet-tasting natural extracts or isolates and these natural extracts or isolates do not comprise the sweet-tasting carbohydrates, in particular sugar or sugar alcohols in a quantity sufficient for releasing a perceptible sweet taste in the preparation. In this respect, within the context of the invention, the sweeteners must be capable on their own of producing a sweetening potency in the preparation to be consumed (foodstuff, indulgence food) which would correspond to the sweetening potency of an at least 4% aqueous sucrose solution.

The naturally occurring sweeteners from group (i) can also be used in the flavoring mixtures according to the invention in the form of extracts or concentrated fractions of these extracts, in particular Thaumatococcus extracts (Katemfe bush), extracts of Stevia ssp. (in particular Stevia rebaudiana), Swingle extract (Momordica or Siratia grosvenorii, luo-han-guo), extracts of licorice root, also Glycerrhyzia ssp. (in particular Glycerrhyzia glabra), Rubus ssp. (in particular Rubus suavissimus), citrus extracts, extracts of Lippia dulcis, correspondingly concentrated fractions of these extracts.

The sucrose equivalence ratio of the sucrose equivalence of the concentration of the substances or substance of group (i) to the sucrose equivalence of the concentration of the substance or substances of group (ii) in the corresponding flavoring mixture (and in other mixtures, cf. further below), is established as follows:

-   1. A comparative series of different sucrose concentrations in water     is produced. Preferred concentrations are 0; 0.25; 0.5; 0.75; 1;     1.5; 2; 3; 4 and 5% by weight sucrose in water. Other     concentrations, in particular higher concentrations, can optionally     also be used for the comparative series. -   2. An aqueous solution of the sweet-tasting substances of group (i)     is produced with an identical concentration of these substances as     in the sample to be investigated (solution 1). -   3. An aqueous solution of the substances of group (ii) is produced     with the same concentration as that of the substances of group (ii)     in the sample to be investigated (solution 2). -   4. A panel of at least 10 people (preferably people experienced in     taste tests, of different ages, backgrounds and sex) tests solution     1 compared to the sucrose series and classifies it in order to     determine the sucrose equivalence. -   5. The determined sucrose equivalence is produced from the average     of individual gradings by the individual panelists. -   6. The dilution ratio is then determined, using which solution 1 can     be set at a sucrose equivalence of 2% by weight sucrose in water.     For this purpose, it can be useful to pre-dilute the test sample     before step 4. It is of course sensible to have the determined     dilution ratio tested once more by the panelists. -   7. Solution 2 (containing the compound(s) of group (ii)) is then     diluted in the dilution ratio determined under 6. -   8. Subsequently, the dilute solution 2 is also tasted and compared     to the sucrose test series, graded by the panelists and a     corresponding sucrose equivalence value is determined (analogously     to points 4. and 5). -   9. The sucrose equivalence of the dilute solution 1 (equivalent to     2% by weight sucrose in water) is put in the ratio to the sucrose     equivalence, determined according to step 8, of the dilute     solution 2. This produces the sucrose equivalence ratio.

The particular advantage of the flavoring mixture according to the invention is that it can be used particularly effectively as a pre-product (or intermediate product) for orally consumable products. The sucrose equivalence ratio which has been set for the substances of groups (i) and (ii) allows the sweetness sensation to be synergistically enhanced. In this respect, it should be noted that the substances of group (ii) (phyllodulcin and the physiologically compatible salts thereof) have a very strongly pronounced sweetening potency (and thus a high sucrose equivalence) even in extremely low concentrations. This means that in the flavoring mixtures according to the invention, the concentration of the substances of group (i) is consistently higher by a multiple than the concentration of the substances of group (ii).

The sweetness sensation which can be produced by the flavoring mixture according to the invention or by the dilutions thereof is significantly higher than the sweetness sensation (which can be measured, for example by the sucrose equivalence) of the compounds of group (i) and of group (ii) added together. Therefore, a surprising synergistic effect is present. This synergistic effect is surprisingly to be observed both in the range below as well as in the range above the perception threshold of phyllodulcin (cf. also further below).

A flavoring mixture according to the invention, comprising an extract of Hydrangea dulcis as the source of the compound or compounds of group (ii) is preferred according to the invention.

In this context, “Hydrangea dulcis” includes all hydrangea variations which contain phyllodulcin. Preferred Hydrangea dulcis variations are Hydrangea macrophylla var. thunbergii, Hydrangea macrophylla var. oamacha and Hydrangea macrophylla var. Amagiana and further hydrangea species which naturally contain phyllodulcin.

In some cases it can be preferable for the extract which is preferably contained according to the invention not to be an aqueous extract, in other words an extract which was not exclusively produced using water as the extraction agent.

The advantage of using extracts of this type is that, surprisingly, the phyllodulcin is more stable, i.e. it exhibits a slower degeneration even under relatively rigid conditions for the foodstuff range. In this respect, reference is also made to FIG. 1 and Example 2 (cf. further below).

Thus, it was possible to observe in an aqueous solution of an exemplary extract a stability which was three times higher with the same absolute starting concentration of phyllodulcin.

The presence (or the containment) of an extract of Hydrangea dulcis (or the preferred hydrangea variations) can preferably be demonstrated by the presence of the compound hydrangenol.

Hydrangenol can also be present in the open form as hydrangeic acid.

For clarification purposes, the structures of the significant ingredients of the extract are combined in the following illustration: phyllodulcin (1), (2S)-phyllodulcin (S-1), hydrangenol (2), (2S)-hydrangenol (S-2), E- and Z-hydrangeic acid (E-3, Z-3).

For the extract of Hydrangea dulcis (in turn preferably Hydrangea macrophylla var. thunbergii) which is preferably to be used according to the invention, it should preferably contain at least 0.1% by weight and at most 50% by weight, preferably 0.5% by weight to 30% by weight, more preferably 1% by weight to 25% by weight of phyllodulcin and at least 0.01% and at most 50%, preferably 0.01% by weight to at most 30% by weight, more preferably 0.01% by weight to at most 25% by weight of hydrangenol, in each case based on the dry weight of the extract.

The extracts, preferably to be used, for the flavoring mixture preferred according to the invention are preferably obtained by a method in which the leaves of the plant which are dried immediately after harvest

-   -   a) are moistened with water and are fermented, moist, at 10 to         50° C., preferably 15 to 25° C. for 1 to 72 hrs, preferably for         5 to 16 hrs;     -   b) the moist, fermented leaves are extracted using a suitable         solvent (for example water, subcritical or supercritical water,         supercritical CO₂, water-ethanol mixtures, ethanol, ethyl         acetate, n-heptane, n-hexane, it also being possible for mineral         or organic acids such as phosphoric acid, citric acid, malic         acid, succinic acid, acetic acid, formic acid, fumaric acid,         maleic acid or other permitted food acids to be used) at a         temperature of from 0° C. to the boiling point of the respective         solvent, under normal pressure, reduced or elevated pressure,         for example by the Soxhlet, counter-flow, percolation or simple         perforated basket methods (primary extract);     -   c) the primary extract is concentrated optionally by         distillative or other evaporative or pervaporative processes;     -   d) the concentrated primary extract is optionally purified by         treating with adsorbing agents (silica gel, activated carbon,         kieselguhr, alumina, basic or acidic or neutral ion exchangers)         in the batch or column methods (secondary extract);     -   e) the secondary extract is dried by evaporative or         pervaporative processes;     -   f) and optionally the dried secondary extract is taken up again         in suitable solvents or mixtures (ethanol, 1,2-propylene glycol,         vegetable oil glycerides, triacetin, glycerol); and     -   g) is adjusted acidically using mineral or organic acids such as         phosphoric acid, citric acid, malic acid, succinic acid, acetic         acid, formic acid, fumaric acid, maleic acid or other permitted         food acids.

Evaporative or pervaporative processes can be, for example distillation, sublimation, water vapor distillation, freeze-drying, pervaporative membrane processes or spray-drying, and suitable auxiliaries and carriers can also be added for this purpose before this treatment.

The process is carried out such that the extract contains 0.1% by weight and at most 50% by weight, preferably 0.5% by weight to 30% by weight, more preferably 1% by weight to 25% by weight of phyllodulcin and at most 50%, preferably 0.01% by weight to at most 30% by weight, more preferably 0.01% by weight to at most 25% by weight of hydrangenol.

A preferred flavoring mixture according to the invention further comprises one or more substances, selected from group (iii), consisting of flavoring and/or aromatic substances which enhance a sweet taste, and the physiologically compatible salts thereof.

Surprisingly, it has been found that in addition to the synergistic effect of sweetness enhancement produced by phyllodulcin or the salts thereof, a further synergistic effect is produced using further sweetness enhancers known from the prior art.

The following are particularly preferred as further sweetness enhancers in this connection:

-   -   Hesperetin according to WO 2007/014879 A1     -   Hydroxyphenylalkadiones according to WO 2007/003527 A1     -   4-hydroxychalkones according to WO 2007/107596 A1 and EP 1 972         203     -   Propenylphenylglycosides (chavicol glycosides) according to EP 1         955 601 A1     -   Divanillins and/or     -   Hydroxyflavans.

The products according to the invention can contain according to group (iii) one or more divanillins, in particular those as described in WO 2004/078302, while 6,6′-dihydroxy-5,5′-dimethoxy-biphenyl-3,3′-dicarbaldehyde is preferred.

The products according to the invention can contain one or more naturally occurring 4-hydroxydihydrochalcones according to group (iii), in particular those as described in WO 2007/107596 and EP 1 972 203. 3-(4-hydroxyphenyl)-1-(2,4-dihydroxyphenyl)propan-1-one (davidigenin) and/or 3-(4-hydroxyphenyl)-1-(2,4,6-trihydroxyphenyl)propan-1-one (phloretin) in particular are preferred.

Hesperetin in the context of an ingredient according to group (iii) of a flavoring mixture according to the invention can be in particular the (2S)-enantiomer, the (2R)-enantiomer or a mixture of these enantiomers, as described in particular in WO 2007/014879.

A flavoring mixture according to the invention can preferably be contained according to group (iii) as propenylphenyl glycoside (chavicol glycoside), the alpha- or beta-anomers and most particularly the beta-anomers of 1-0-[4-(propen-2-enyl)phenyl]-D-glucopyranoside (chavicol glucoside), 1-0-[4-(propen-2-enyl)phenyl]-6-0-β-D-apiofuranosyl-D-glucopyranoside (furcatin), 1-0-[4-(Propen-2-enyl)phenyl]-6-0-β-D-rutinoside and/or of 1-0-[4-(propen-2-enyl)phenyl]-O-β-D-xylopyranosyl-(1-6)-β-D-glucopyranoside (p-allylphenylprimeveroside, miyaginin).

Isogingerdione-2 is preferred as hydroxyphenylalkane dione.

3′,7-dihydroxy-4′-methoxyflavan and/or (S)-3′,7-dihydroxy-4′-methoxyflavan is preferred as hydroxyl flavan.

Within the context of the objects set above, the invention also relates to an orally consumable product, comprising a flavoring mixture according to the invention. In the product according to the invention, the ratio of the sucrose equivalence of the concentration of the substance or substances of group (i) to the sucrose equivalence of the concentration of the substance or substances of group (ii) is ≥2, preferably ≥3, more preferably ≥4 and particularly preferably ≥6. Within this range, the synergistic enhancing effect of phyllodulcin can be utilized particularly effectively, such that the orally consumable product is ultimately obtained with a significantly reduced use of concentrations of compounds of group (i), while the sweetness remains the same.

Of course, the orally consumable product according to the invention optionally comprises one or more further conventional foodstuff ingredients.

The concentration of the flavoring mixture in the orally consumable product is preferably set such that the concentration of the substances of group (ii) is from 0.5 to 15 ppm, based on the weight of the product.

The synergistic effect of phyllodulcin and the salts thereof in respect of the sweetness enhancement can be utilized even in this low concentration. This is surprising in view of the prior art. Furthermore, the use of such reduced concentrations of phyllodulcin in the orally consumable product (and of course particularly in the end product) had the advantage that unpleasant secondary flavoring notes of phyllodulcin are not detected or are only detected without being disturbing. Thus, phyllodulcin has already been described as a sweetener (Crosby, G. A. (1976). “New Sweeteners.” Critical Reviews in Food Science and Nutrition (June): 297-323). However, this document described the strong secondary taste and also an aftertaste as serious disadvantages. The result of this was that in spite of the significant sweetening effect of phyllodulcin, hitherto it has not been routinely used as a sweetener.

An orally consumable product according to the invention is preferred in which the concentration of the flavoring mixture is adjusted such that the concentration of the substances of group (i) alone has a sucrose equivalence of a solution of ≥4% by weight, preferably ≥6% by weight of sucrose in water.

Surprisingly, the synergistic enhancing effect of the sweetening action released by phyllodulcin or the salts thereof can be achieved particularly well in orally consumable products in which the concentration of the substances of group (i) is adjusted such that it has a sucrose equivalence of more than or equal to 4% by weight, preferably more than or equal to 6% by weight of sucrose in water.

In the orally consumable products according to the invention, the upper limit for phyllodulcin is preferably 15 ppm, more preferably 10 ppm, more preferably 5 ppm and, if it is present, the upper limit for hydrangenol is 50 ppm, the preferred lower limit for hydrangenol being 0.01 ppm, in each case based on the total weight of the orally consumable product.

According to the invention, it is further preferred that if an extract of Hydrangea dulcis is contained in the product according to the invention, this extract also contributes to the complete flavoring of the product with a non-sweet flavoring note.

Preferred according to the invention is a flavoring mixture of the invention in which the substance or substances of group (iii) is/are selected from the group consisting of:

-   -   hesperetin     -   phloretin     -   3′,7-dihydroxy-4′-methoxyflavan and     -   (S)-3′,7-dihydroxy-4′-methoxyflavan.

Furthermore, a flavoring mixture according to the invention is preferred which contains one or more further flavorings, auxiliaries and/or carriers.

In addition, it is preferred that phyllodulcin is present in the flavoring mixtures according to the invention, being concentrated in the S form (cf. formula S-1). The enantiomer excess is preferably between 1 and 100%.

Most particularly preferred according to the invention is an orally consumable sweet-tasting product, comprising

(i) one or more naturally occurring sweet-tasting substances including the physiologically compatible salts thereof, preferably selected from the group consisting of:

-   -   a) carbohydrates (sugars), selected from the subgroup consisting         of sucrose, D-fructose, D-glucose and plant preparations         containing one or more of the mentioned carbohydrates,         (preferably in a proportion of at least 5% by weight, preferably         at least 15% by weight), and these carbohydrates can also be         present as a natural or synthetically produced mixture (for         example as honey, invert sugar syrup, high fructose corn syrup);     -   b) sugar alcohols selected from the subgroup consisting of         glycerol and erythritol,     -   d) sweeteners selected from the subgroup consisting of         stevioside, rebaudioside A and rubusoside, and extracts or         concentrated fractions of these extracts can also be used, for         example Stevia extracts and Rubus suavissimus extracts,     -   alone or in mixtures     -   provided that the sweetness of the mentioned sweet-tasting         substances of group (i) jointly in the orally consumable         sweet-tasting product according to the invention is sensorially         equivalent to an at least 6% aqueous sucrose solution,         and         ii) an extract of Hydrangea macrophylla var. thunbergii         (Makino), comprising phyllodulcin and hydrangenol in a         concentration such that, based on the orally consumable         sweet-tasting product, at least 0.00005% by weight (0.5 ppm) and         at most 0.0015% by weight (15 ppm) of phyllodulcin and at least         0.000001% by weight and at most 0.0050% by weight of hydrangenol         are contained, the extract also having a non-sweet flavoring and         taste characteristic         and         (iii) one or more sweetness-enhancing flavoring and/or aromatic         substances including the physiologically compatible salts         thereof, in each case selected from the group consisting of     -   hesperetin     -   phloretin     -   3′,7-dihydroxy-4′-methoxyflavan or         (S)-3′,7-dihydroxy-4′-methoxyflavan         and optionally         (iv) one or more further conventional foodstuff ingredients,         flavorings, auxiliaries or carriers.

As mentioned, in the orally consumable, sweet-tasting products according to the invention, the concentrations of the compounds of group (i) are preferably overall sensorially equivalent to a ≥4% by weight, preferably 6% by weight aqueous sucrose solution. However, in this respect the ratio of the naturally occurring sweet-tasting substances of group (i) among one another can be freely selected. In this case, the compounds of groups (i) a) and/or (i) b) are preferably used in a concentration sensorially equivalent to an at least 3%, preferably 5% by weight aqueous sucrose solution and the compounds of groups (i) c) and/or (i) d) are preferably used in a concentration sensorially equivalent to an most 2% by weight, preferably at most 1% by weight aqueous sucrose solution. A reduction in sugar can be achieved particularly effectively in this manner, without any impairment to the taste sensation.

Surprisingly, it has been found that in the orally consumable, sweet-tasting products according to the invention, the sweetness is enhanced to a substantially greater extent (not additively, but synergistically, cf. above as well and Examples) than in comparative products which do not contain this combination according to the invention. In particular, the use of the extract in the form and concentration described above is advantageous due to the flavoring characteristics which are present and which round off the sweetness profile of the orally consumable, sweet-tasting products according to the invention, making it more similar to sugar and more stable.

An orally consumable product according to the invention is preferred which is selected from the group consisting of a pharmaceutical preparation, an oral care preparation, a semi-finished product and a liquid or solid foodstuff.

The orally consumable product is more preferably a sweet-tasting drink which can also be carbonized, and comprises

The orally consumable, sweet-tasting products according to the invention are routinely products which are intended to be introduced into the human oral cavity, to remain there for a certain period of time and then to either be consumed (for example ready-to-eat foodstuff) or removed again from the oral cavity (for example chewing gum or toothpaste). It is understood that the use of the flavoring mixture according to the invention can be provided for any type of such products. Included with these products are all substances or products which are intended to be received in the human oral cavity in a processed, part-processed or unprocessed state. This also includes substances which are added to foodstuffs during the production, processing or treatment thereof and are intended to be introduced into the human oral cavity.

It is understood that the flavoring mixture according to the invention can be used in particular in foodstuffs. In the present context, the term “foodstuff” is understood in particular as meaning substances which are intended to be swallowed by humans in an unaltered state or in a prepared or processed state and then consumed; the term “foodstuff” is also understood as meaning sheathings, coatings or other encapsulations which are intended to also be swallowed, or for which swallowing is to be envisaged. Specific products which are usually removed from the oral cavity (for example chewing gum) are also understood as a foodstuff in the present context, since it cannot be ruled out that at least portions thereof are swallowed.

The flavoring mixture according to the invention is used in particular in ready-to-eat foodstuffs. The term “ready-to-eat foodstuff” is understood in this context as meaning a foodstuff which is already fully constituted in respect of the substances which determine the taste. The term “ready-to-eat foodstuff” also includes corresponding drinks as well as solid or semi-solid ready-to-eat foodstuffs. Examples include deep-frozen products which, before consumption, have to be defrosted and heated to consumption temperature. Products such as yoghurt or ice cream, but also chewing gum or hard caramels are also included as ready-to-eat foodstuffs.

An oral care preparation (also called an oral hygiene product or oral hygiene preparation) in the context of the invention is understood as meaning a preparation for cleaning and caring for the oral cavity and throat and also for freshening breath. This explicitly includes care of the teeth and gums. Application forms of conventional oral hygiene formulations are creams, gels, pastes, foams, emulsions, suspensions, aerosols, sprays as well as capsules, granules, pastilles, tablets, candies or chewing gums, on the understanding that this list is not restrictive for the purposes of this invention.

As already mentioned, the flavoring mixture according to the invention can also be used in semi-finished foodstuff products. The term “semi-finished foodstuff product” relates in this respect to foodstuffs which are intended to be consumed only in a further processed state, for example after the addition of flavorings or aromatic substances which (co)determine the sensory impression.

According to what has been stated above, the invention also relates to the use of a flavoring mixture according to the invention for the production of a reduced-sweetener orally consumable product.

As already described above in depth, this use makes it possible to produce a given taste sensation (sweetness), at the same time with a reduction in the use of sweet-tasting substances according to group (i).

Furthermore, the invention also relates to the use of an extract of Hydrangea dulcis for the production of an orally consumable product with a stabilized content of a compound or compounds, selected from group (ii), consisting of phyllodulcin and the physiologically compatible salts thereof, the product comprising one or more sweet-tasting substances, selected from group (i) of naturally occurring sweet-tasting substances and the physiologically compatible salts thereof without phyllodulcin and the physiologically compatible salts thereof.

In this manner, it is possible to provide flavoring mixtures and orally consumable end products in which the proportion of phyllodulcin or the salts thereof is stabilized such that the advantageous effect of these compounds can also be used over a reduced period of time.

In the following, the invention will be further described on the basis of examples and the claims. The examples serve to illustrate the invention, without restricting the scope of protection of the claims. All quantities relate to weight, unless indicated otherwise.

EXAMPLES Example 1 Consecutive Extraction of Hydrangea dulcis

100 g of plant material (mainly leaves) dried directly from/out of the living plant (Hydrangea dulcis) are moistened with deionized water and left to stand for 16 hrs at room temperature such that fermentation takes place. The fermented plant material is dried again for 3 hrs at 40° C. 100 g of the fermented, dried plant material is then extracted with stirring using different solvents in increasing polarity (heptane, methylene chloride, ethyl acetate, ethanol/water 4:1) for 1 hour in each case at room temperature. The solvent is removed under vacuum and the dried extracts are tasted in a dose of 500 ppm on sugar solution (5%) and salt solution (0.5%) and assessed sensorially.

Content of phyllodulcin (based Solvent Yield on dry mass) Sensory assessment Heptane 0.8 g 12.7% Herby, sweet, sweetener note Methylene 1.6 g 15.4% Sweetener note, licorice, chloride bitter Ethyl acetate 1.7 g 10.5% Bitter, sweet, green, herby Ethanol/water 20.2 g  1.4% Bitter, sweet, herby

Example 2 Production of an Ethanolic Hydrangea dulcis Dry Extract

2 g of dried fermented plant material (produced as described in Example 1) were extracted in 50 ml of ethanol for one hour under reflux. The solvent was removed under vacuum and the dried extract was tasted in a dose of 110 ppm on sugar solution (5%) and assessed sensorially.

Content of phyllodulcin (based Solvent Yield on dry mass) Sensory assessment Ethanol 0.29 g 7.2% Herby, sweet, licorice, depth, woody

The exemplary extract was tested for stability under an elevated thermal stress in comparison to pure phyllodulcin. A solution of 100 mg/l of phyllodulcin and 1.38% of the exemplary ethanolic extract (corresponds to 100 mg of phyllodulcin) in an aqueous phosphate buffer, adjusted to pH 9, was tested immediately after preparation and then at regular weekly intervals for its phyllodulcin content. In this respect, an aliquot of the respective test solution was separated in an HPLC installation (RP phase) and quantified by UV detection compared to a calibration with pure phyllodulcin. The samples were stored at 40° C. in closed glass vessels to prevent evaporation. The phyllodulcin contents of the test solutions are plotted against time in FIG. 1.

As can clearly be seen from FIG. 1, pure phyllodulcin is decomposed more rapidly than a comparable quantity of phyllodulcin in the form of an extract according to the invention. In a rough estimation, the stability is approximately tripled.

Example 3 Production of an Ethyl Acetate Hydrangea dulcis Dry Extract

2 g of dried fermented plant material (produced as described in Example 1) were extracted in 50 ml of ethyl acetate for one hour at 40° C. with stirring. The solvent was removed under vacuum and the dried extract was tasted in a dose of 55 ppm on sugar solution (5%) and assessed sensorially.

Content of phyllodulcin (based Solvent Yield on dry mass) Sensory assessment Ethyl acetate 0.1 mg 14.4% Herby, sweet, similar to sweetener

Example 4 Production of an Ethanolic/Aqueous Hydrangea dulcis Dry Extract

2 g of dried fermented plant material (produced as described in Example 1) were extracted in 50 ml of ethanol/water (7:3) for one hour at room temperature with stirring. The solvent was removed under vacuum and the dried extract was tasted in a dose of 145 ppm on sugar solution (5%) and assessed sensorially.

Application Example 1 Sweetness Enhancement Using Hydrangea dulcis Extracts Preliminary Test: Inherent Sweetness of the Extract

The inherent sweetness of the extract from Example 2 (containing 7.2% by weight of phyllodulcin, based on dry mass) which was dissolved in different concentrations in pure form in water (0.0010, 0.0025, 0.0050, 0.0100, 0.0250, 0.0500% by weight in water) was determined using a comparative series of different sucrose concentrations in water (0, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4 and 5% by weight sucrose in water). The panelists were requested to test and grade each individual extract solution compared to the sucrose series (sucrose equivalence). The inherent sweetness of the extract for the concentrations mentioned above could be determined from the results obtained from the panelists.

Concentration of the extract Phyllodulcin Determination from Example 2 in water concentration of the sucrose Other sensory [% by weight] in ppm equivalence in water description 0.0010 0.7  0.2% Tea note 0.0025 1.75 0.45% Tea note, hay 0.0050 3.5 0.64% Green tea 0.0100 7 0.83% Fennel, aniseed, black tea, slightly bitter 0.0250 17.5 1.78% Strong tea note, green, fishy, slightly bitter 0.0500 35 2.7 Licorice root, fishy, astringent, tea, hay, bitter

It can be seen by extrapolation from the Table that it is possible to achieve a sucrose equivalence of 1.5% with approximately 200 ppm of the extract (corresponding to approximately 15 ppm of phyllodulcin) and 1% with approximately 150 ppm of the extract (corresponding to approximately 10 ppm of phyllodulcin).

Enhancement of the Sweetness Sensation of a Sucrose Solution

In order to quantify the enhancement of the sweetness sensation, the sweetness of a 5% sucrose solution and of a sample containing 5% of sucrose and an amount of the test substance or of the test extract, was determined by a group of experts (grade 1 [not sweet] to grade 10 [extremely sweet]). The evaluation was made as a calculation of the reduction (in %) of the sweetness sensation from the averages of the assessments of the sucrose solution or of the sucrose and the test substance or of the solution containing the test extract.

Extract concentration Sweetness % Enhancement (ppm)/phyllodulcin sensation (1-10) of the sweetness Substance/extract concentration (ppm) without with sensation Ethanolic extract from 10/0.7 5.0 ± 0.8 5.4 ± 1.5 8% Example 2 (contains 7.2% phyllodulcin) Ethanolic extract from  25/1.75 5.6 ± 1.2 5.9 ± 1.1 6% Example 2 (contains 7.2% phyllodulcin) Ethanolic extract from 50/3.5 5.3 ± 1.3 6.9 ± 1.5 31% (p < 0.01)  Example 2 (contains 7.2% phyllodulcin) Ethanolic extract from 100/7   5.5 ± 0.9 7.4 ± 1.3 34% (p < 0.001) Example 2 (contains 7.2% phyllodulcin) Ethanolic extract from 110/7.7  5.6 ± 1.7 7.5 ± 1.8 33% (p < 0.01)  Example 2 (contains 7.2% phyllodulcin) Ethanolic extract from 200/14  5.1 ± 0.8 7.6 ± 1.3 49% (p < 0.001) Example 2 (contains 7.2% phyllodulcin) Ethyl acetate extract from 55/7.7 4.9 ± 1.1 6.9 ± 1.3 42% (p < 0.001) Example 3 (contains 14.4% phyllodulcin) Ethanolic/aqueous extract from 145/7.7  5.3 ± 1.6 6.9 ± 1.5 30% (p < 0.01)  Example 4 (contains 5.3% phyllodulcin) Ethanolic/aqueous extract from 240/7.7  5.3 ± 1.1 7.6 ± 1.6 43% (p < 0.001) Example 5 (contains 3.2% phyllodulcin)

It is possible to detect a very good sweetness enhancement even with the concentration of approximately 100 ppm ethanolic extract, which is not sweet per se, from Example 2, corresponding to less than 10 ppm of phyllodulcin. Purely by way of calculation, it would be expected that a 5% sucrose solution (corresponds sensorially by definition to 5% sucrose equivalents) which contains 100 ppm of ethanolic extract from Example 2, would produce additively a sweetness of approximately 5.8 sucrose equivalents. However, the sensory assessment of a mixed solution of this type of 5% sucrose with 100 ppm of the extract according to the invention from Example 2 produced by the method described in the preliminary test, a sucrose equivalence of 7.7%, which corresponds to a synergy of more than 30% above the expected value.

The ingredients were mixed in the stated sequence and made up to 100% with water. The mixtures were poured into glass bottles and carbonized.

The preparations were tested sensorially in blind duo tests. In this respect, the sweetness was assessed by experts using a grading of 1 [not sweet to 10 [extremely sweet].

Comparison between 1st Significance and 2nd Sweetness sensation (1-10) (n.s. = not samples 1st sample 2nd sample Change (%) significant) A and B 7.1 ± 1.4 4.6 ± 1.3 −36% p < 0.001 A and C 6.3 ± 1.2 4.6 ± 1.9 −28% p < 0.01  A and D 6.9 ± 1.4 7.0 ± 1.5  2% n.s.

By omitting sugar (20% by weight, based on sucrose), a reduction in sweetness of approximately 36% was observed (preparations A and B).

As comparison (preparation C), the known sweetener neohesperidin dihydrochalcone was used in a concentration which alone in water corresponds to approximately 0.5% sucrose equivalence (determined by the method mentioned in Application example 1, first part). Compared to Comparative example A, the sweetness of the comparative preparation C, reduced in sugar by 20%, could not be reproduced alone by 1 ppm of neohesperidin dihydrochalcone.

By adding the extracts according to the invention on their own (preparations D and E) to the reduced-sugar preparation, the panelists were no longer able to detect any significant difference between the full sugar preparation and the relatively sugar-depleted preparation according to the invention (A as opposed to D or A as opposed to E); however, with the lower dosing (preparation E), it was still possible to detect a sweetness which was not completely reproduced.

This means that the extracts according to the invention are better able to reproduce the sweetness of reduced-sucrose applications than conventional sweeteners in low dosings of less than 1% sucrose equivalent.

However, by combining the lower dosing of 50 ppm of the extract of the invention according to Example 2 with known flavorings for sweetness enhancement (G, H), the sweetness could then be substantially reproduced or even more sweetness could be achieved by using extracts of Rubus suavissimus (F).
